Dual-layer Disc (PS3)?

Hey, does anyone know if the PS3 version is on a dual-layer disc? If it is then it would have BPDL printed on the underside of the disc, otherwise it would have BPSS printed there.

My slim has some bluray issues and is having lots of trouble picking up dual-layer discs (including Uncharted 3, to my frustration). Being out of warranty, I'd rather put my money towards fixing my PC first, meaning I won't be able to get around to fixing my PS3 until the new year. It picks up single layer discs just fine though, so if this is single-layer I'll be sure to pick it up.
